8(7laims. (c1. zsa-as) The liquid atomizer forming the object of the larger scale in section taken on line l2l2 of invention, which is designed chiefly to be carried F18. 13, and in lady's handbags, traveling bags or the like, Fig. 13 a top plan view of the atomizer neck. has, in known manner a pressure pump con- The liquid atomizer consists of a lower part I I 5 structed as a flat extensible vessel, one part of and of an upper part 2 of a vessel extensible to 6 the vessel containing pistons wound around with a limited degree, of substantially flat, preferably springs and the other part cylinders for receiving profiled form. Pistons 6 having each a packing the pistons. The chief characteristic feature of collar I on the front face are standing on the the invention is that the nozzles for the combottom of part I, are wound round with springs 5, pressed air and for the liquid are located at extending into cylinders 4 of the extensible part 10 the height of the mouth of a neck on the exten- 2, the latter being forced up on part I by the sible part of the vessel and that on the neck a action of the springs.

Acontainer ill of rectangular shape 15 same and at the same time shut off the outlet is flxei' n the extensible part 2 on the top plate for the spray jet. This presents the serious 2a of the same and between the two cylinders 4 advantage that the atomizer if not in use-for and holds the liquid to be atomized, for instance instance when accommodated in a lady's handperfume.

In order to g ifggzg zg 9 construction and m the securelylrsdetermine this overlapping position the sleeve in the form of construction shown- Fig. 10 is a sectional view of the upper parts of has on u i r urface projections 2| and pins he q d a o r taken On e Iii-l0 0f 22 vertically projecting from these proJections, 11 e neck p Of the q f o er on said pins being guided in arcuate slots 23 in the larger scale in section taken on hne l|--ll of top plate 2a, as is clearly shown in Figs. 5 to '7. Fig. 13, A bridge 24 extending over the atomizer tubes Fig. 12 the neck part of the liquid atomizer on H, Ha, I! in the neck l2 serves to protect the atomizer tubes and to separate the liquid from the air path when liquid is being filled into the container.

By turning sleeve i5 into the position shown in Figs. 3 and 6 the claws of part I come into register with the recesses I! in collar Ila so that the now unlocked part 2 is pushed out of part I by the action of the springs 5. A pumping eifect produced by alternately pressing down and releasing top plate 2a of part 2 causes the ejection of a spraying jet, which can be freely ejected as during the turning of sleeve l5 the aperture It in the wall of this sleeve has come into register with the aperture il in neck I 2 of the atomizer. (Fig. 2.)

To stop the atomizing the extensible part 2 is locked on part i (Fig. 4) in its lower position by turning back sleeve l5 so that aperture ll of neck I2 is covered by the wall of the sleeve and leaking of liquid from the atomizer is prevented.

To avoid under any circumstances drops of liquid remaining on the sleeve, such drops forming if air compressed during the inserting of the extensible part into the bottom part of the vessel draws along some liquid which then passes through in the form of drops between neck and sleeve which has been moved into the closing spraying aperture, to appear in the bore of the position, an automatic closing valve is arranged as shown in Figs. 9 to 13 in the outlet tube or channel for the compressed air, said valve shutting off the channel for the compressed air as soon as the pumping effect ceases.

A connecting tube 35 between the cylinders 34 leads to the bore of a stopper 26 in bush 38 inserted into the neck 31 of the atomizer vessel. The riser tube 40 is inserted in a removable stopper 28, 28a opposite a bore 21 in the stopper 26. The bore 21 branches horizontally from a channel 25a arranged axially to the bore 25 and closed by a screw 29. On the lower end of the channel 25a rests a valve ball 30 which is pressed upon its seat by means of a spring ii. In the neck 31 a hole 36 is provided at the height of the liquid nozzle, a hole H in the wall of bush 38 and a hole 42 in the tumable sleeve 39, these holes forming together an outlet for the spraying jet, as shown in Fig. 10.

Neck 3'! serves also in this form of construction as pivot pin for the tumable sleeve 39 and as charging tube for the container 43, if the stopper 28, 28a cut out at an angle and fitted with riser tube 40 has been pulled out. An external screw thread 32 at the upper portion of neck 31 serves for the reception of an internal screw threaded closing cap 33 (Fig. 10).

The formation of the spraying jet takes place in that the air forced out of the cylinders 34 by the pistons fiows through the transverse tube 35 into the channel 25, lifts the ball 20 in opposition to the action of the spring, fiows through channel 3| and fiows out through the hole 21, the air drawing liquid from the nozzle of tube ll and atomizes this liquid.

As during the turning of sleeve 3! the aperture 42 in the wall of the-same comes into register with the aperture 38 in the neck 31 of the atomizer and with the aperture ll in bush 2', this latter opening is liberated so that the spraying jet can be ejected (Fig. 10).

As soon as the pumping effect and therewith the inflow of compressed air through channel 25 ceases, the spring 3| will press the ball 30 upon its seat, and any outflow of air which might draw along any liquid is prevented with certainty.
